IMPROVEMENT IN HOPPERS FOR BLAST-FURNACES.

Specification forming part of Letters Patent No. 127,214, dated May 28,1872.

Specification describing a Feed-Hopper for Blast-Furnaces, invented byDENNIS BAUMAN, of Parryville, in the county of Carbon and State ofPennsylvania.

The invention consists in a hopper provided with adouble-inclinedvalve,movable thereunder, so as to feed the fuelsimultaneously to the circumference and intermediate space of fire-box.

Figure 1 is a vertical section, and Fig. 2 a plan view of my invention.

A represents the mouth offire-box, and B the hopper, with or without asliding funnel, 9. (J is a eentrally-apertured valve, having twocircular inclines or chutes, e f, at an angle to each other. It is alsosuspended to a lever or beam, D. E is an ovoidal or otherwisesuitably-shaped pendant.

The space between the funnel g and pendant E constitutes the valve-seatof hopper. This valve-seat is covered by the elevation of valve 0 anduncovered by the depression of said valve. When the latter takes placethe fuel in hopper B falls upon the two inclines e f, and

is at the same time distributed both around the circumference and overthe intermediate space of fire-box. The feed being completed, the valveis drawn up, the valve-seat covered, and the lever 1) made fast.

I am aware that a valve has been used to distribute the fuelcircumferentially; also one which distributed it centrally; and againone which could do both at two distinct and separate operations; butnone that can perform the two functions simultaneously, as is done by mymachines.

What, therefore, I claim as new, and desire to protect by LettersPatent, is-

The combination, with a hopper, B, provided with a central pendant, E,of the centrallyapertured valve 0, having the two inclines e f at anangle to each other, and arranged to move up and down under said hopper,as and for the purpose described.

DENNIS BAUMAN.
